Present study attempted to identify and enumerate micro organisms spoiling commonly used cosmetics samples. Among 20 brands of total 6 categories of samples studied (soap, shampoo, lotion, face wash, cream and petroleum), almost all were found to be rigorously contaminated with total viable bacteria within a range of 10 3-10 5 cfu/g. Proliferation of fungal species was observed up to 10 3 cfu/g. Prevalence of Staphylococcus sp., Pseudomonas sp. and Bacillus sp. was observed within a range of 10 1-10 3 cfu/g while actinomycetes were completely absent. Among the enteric bacteria, Escherichia coli was found completely absent from all the samples tested, however, the prevalence of Klebsiella sp. was noted up to 10 1 cfu/g. Such findings highlighted a great public health risk associated with skin diseases among the users and thereby specified the importance to introduce a proper guideline in maintaining good microbiological quality for such topically used healthcare products.
Export quality frozen shrimps comprise as one of the major economic interests in Bangladesh. During cultivation or processing and packaging, microbial condition is an important issue to maintain the quality of shrimps. Eight shrimp samples, of which, one from hatchery, 3 from local markets and 4 processed export quality samples were studied for microbiological risk assessment (MRA). One hatchery, three market and two export quality shrimp samples were found to contain bacterial pathogens probationary identified as Escherichia coli, Klebsiella spp., Vibrio spp., Aeromonas spp., Pseudomonas spp., Listeria spp., Shigella-like organisms, Staphylococcus aureus, and Salmonella spp. and two other processed export quality shrimp samples were completely free of pathogens of any type. Surprisingly, the later two processed export quality shrimp samples showed antibacterial activity against E. coli, Klebsiella sp. and Vibrio sp.Bangladesh J Microbiol, Volume 29, Number 1, June 2012, pp 7-10
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
